PHOTOGRAPHIC REPRODUGING APIPARATUS Application filed January 4, 1928.

The object of the present invention is to provide a photographicreproducing appa ratus adapted to reproduce by enlargement, reduction ornormal size a picture of any kind by-reflection and a film image byprojection, the elements being so designed and co-related to facilitatesuch reproduction and perform it accurately and enable duplication ofthe reproductions rapidly.

The invention will be described with reference to the accompanyingdrawings, in

The apparatus comprises a supporting table having the legs 1, 1 1,horizontal frame members 2 and the horizontal sup porting top The member3 is provided 7, the latter carrying a Serial No. 244,388.

with an image opening 4 surrounded by the neck 5 of a bellows 5, thelower end of the bellows being connected to a lens support lens 8. At 9is indicated a mounting for carrying any suitable type of constantlyopen shutter, the only requirement being that the opening in the shutterbe adjustable. For this purpose an adjustingarm 10 (Fig. 1) may beemployed. Lens support 7 at its lower end is connected to a bellows 11,at the lower end of which is a rectangular bellows frame 12.

When it is desired to reproduce pictures printed upon or otherwisecarried by opaque sheets, such sheets are placed in the illuminatingframe as shown in Figure 12. This frame has horizontal flanges 13adapted to lie in a shallow rectangular depression formed in negativeframe 14. The sheet bearing the picture may lie upon the horizontalbottom wall of the illuminating frame, one of such picture sheets beingindicated at 15, Figure 2. The flanges 13 of the illuminating frame maysupport lamps 16 each having a reflector 16 for throwing the light downupon the picture sheet. The image is thus thrown, by reflection,upwardly through the shutter opening and through the focusing lens 9,thence through image opening 4 upon a sensitized body such as the sheetnow to be described.

Carried by table member is a holder 17 which, in the present instance,is depressed below the top of the table. Holder 17 is adapted to receivea removable box 18 having at opposite sides shaft receiving troughmembers 19 for the shaft 20 of a roll of sensitized material in sheetform indicated at 21. Box 18 may have .a removable cover 22 and a slot23 for the passage of the strip. A guide roll 24 may lie under the stripnear the point of its emergence from the box. The strip passes overimage opening 4 and thence over a feed roll 25 (Figure 6), the feed rollbeing on a shaft 26 carried by a roll releasing member which is shown indetail in Figure 11, the member being indicated at 27. Roll releasingmember comprises spaced parallel arms each arm .having a cam member 27*adapted to bear upon a fixed contact member 28. A finger piece 29 isprovided for the roll releasing member.

Shaft 26 passes through bearing blocks 30, one block being disposedadjacent each cam member 27 and each block being engaged by a spring 31,the compression of which is regulated by an adjusting screw 32. Thearrangement is such that when finger piece 29 is depressed, cam members27 X are thrown against fixed contacts 28 and shaft 26 is depressedagainst the tension of spring 31, thus carrying roll downwardly.

When roll 25 is brought downwardly, the sensitized sheet 21 may bepassed over the lower roll and under upper roll 33. Upper roll 33 ismounted in the bearing bosses of opposed brackets 34 and its shaft 35carries at one end a ratchet disk 36 adapted to be engaged by theratchet end 37* of a pinion 37. Pinion 37 is adapted for engagement witha rack 38 which is held in normal position by means of a spring 39 andis adapted to be moved endwise by cable 40. Cable 40 is led over apulley 41-and thence downward through an opening 42 in table member 3.The cable passes through a guide tube 43, thence over a pulley 44 to thefront of the apparatus and thence over a pulley 45 to a connection 46with an operating lever 47, having a foot pedal 48, the lever beingguided by vertical bars 49 secured by arms to leg 1".

It will thus be seen from the above description that foot pressure uponpedal 48 will rock lever 47' and impart endwise movement to rack 38through cable 40. The length of this movement may be adjusted byproviding means for changing the effective length of movement of lever47.

In the position of the elements in Figure 3 a movement of cable 40 tothe right imparts a similar movement to rack 48 and pinion 37 is rotatedto the left thus causing a positive engagement between the ratchet disksand consequent rotation of roll 33. This movement will carry sensitizedstrip 21 to the right a distance proportionate to the rotation of roll33. \Vhen the cable is released, however,.disk 37 will be rotated idlywithout affecting disk 36 or roll 33.

Referring again to Figure 3 it will be seen that at the right hand endof table member 3 there is pivoted at 51 a knife blade 52 haying afinger piece 53,'the parts being illustrated in perspective, Figure 1.Thus when the exposed portion of the sheet has been fed past the knife,the latter may be actuated to sever such portion from the sheet. Theknife may be held in upper inactive position by means of a light spring54. Lens support 7 is carried by spaced arms 55, 55*, the first armlying against a vertical plate 56 carried by supporting bar 57 and thesecond arm 55*, lying adjacent a plate 58 carried by vertical bar 59.Arm 55* car ries a roll 60 running on a flanged extension of plate 58and arm 55 carries a roll 61 adapted to run on a flanged extension ofplate 56. On the inner face of bar 57 is a vertical rack 62 engaged by apinion 63 on a shaft 64. Shaft 64 carries a second pinion 65 engaging arack 66 carried by a vertical bar 59. Exterior of plate 55 shaft 64 calries a worm wheel 67 engaged by a worm. 68 on a shaft 69 operable bycrank 70. Plate 55 carries a pointer a adapted to register with a scale5 on bar 56.

Negative frame 14'is carried by spaced arms and is given verticalmovements exactly in the same manner as the lens support 7. Thesupporting arms for the negative frame are indicated at 71, 71*,Figure 1. Arms 71, 71 support a shaft 72 which carries a worm wheel 73,Fig. 2, engaged by a worm 74 on a shaft 75 operable by a handle 76.Shaft 72 also carries a pinion (not shown) in engagement with rack 62and a second pinion 77 in engagement with rack 66. The arm 71 carriesguide rolls in engagement with the above described trackways on theracks 62, 66. By rotating handle 76 the negative frame may be adjustedrelatively to the focusing lens.

The negative frame is best shown by the sectional'view, Figure 8, andthe plan view, Figure 4. It comprises a rectangular frame indicatedgenerally by the numeral 14 having opposed horizontal slots for theadjusting plates 78, 7 8 and, at right angles thereto. opposed slots forthe reception of the adjusting plates 79, 79. Plate 78 carries opposedracks 80 connected by pinions 81 with racks 82, carried by plate 78".Thus movement of plate 78 will be communicated to plate 7 8*, and inwardmovement of one plate imparting the same movement to the other.Adjusting plate 79 carries racks 83 connected by pinions 84 with racks85 carried by adjusting plate 79*. Thus movement of plate 79 inwardlywill impart a similar movement to plate 79 and vice versa. The negativeframe also has a suitable opening to receive a film holder 86 having ahandle 86*, the frame of the film holder having a side depression 87 sothat when the holder is inserted within the negative frame it is pushedforwardly until a depression is entered by eccentriepin 88 carried by aspring bar 89. The bar may be given a slight movement to withdraw thepin by rocking it through crank 90. The film holder has a transparentbase 86 to receive a film or plate and when a film is used it may becovered by a second glass plate as customary, in order to hold it flat.

It will be seen by reference to Figure 8 that the film holder rests onor above adjusting plates 78, 78*. 79, 79*. The adjusting plates controlthe size of the area. for the passage of the light rays from the lampIll C house to the film or plate holding the image. raising or loweringthe negative frame and It will be seen that the table 3 is provided lamphouse or illuminating frame.
